Can the 'Great Green Wall' stop desertification in China?

China is one of the countries worst affected by desertification. As the Gobi Desert expands further south - engulfing an average of 3,000 square kilometres every year - entire communities are forced to relocate, becoming climate refugees. In a bid to combat this phenomenon, Chinese authorities have been erecting a so-called "Great Green Wall" of vegetation. In some areas, positive results are beginning to show. Our France 2 colleagues report, with FRANCE 24's Ellen Gainsford.
